PAPER BOX.

SPECIFICATION forming part of Letters Patent No. 579,590, dated March 30, 1897.

Application filed July 16, 1896. $erial No. 599,353. (No model.)

T 0 all whom it may concern:

Be it known that I, FRANK Knosnnocn, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented a certain new and useful Improvement in Paper Boxes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to certain new and useful improvements in paper boxes and applies more particularly to the box itself, though it may be used on the lids also. It belongs to that class in which the detached portions integral with the sides or bottom are turned in at right angles thereto and properly locked in place to form a rectangularbox without the use of glue. l-Ieretofore in preparing the blanks for folding to form a box there has been a greater or less waste of material by reason of the use of tongues and extensions either for reinforcing the sides or making the lock. My present improvement is designed to avoid that and to form a box from a square or rectangular piece of paper or cardboard with little or no waste.

In the accompanying drawings, Figure 1 is a plan view of a blank cut and scored or creased and adapted to be folded into a box or lid of a box embodying my invention. Fig. 2 is a perspective view of a box formed from a blank such as is shown in Fig. 1. Fig. 3 is a plan View of a blank cut and scored or creased and adapted to be folded into a box and lid all from a single blank. Fig. 4 is a perspective view of a box formed from the blank shown in Fig. 3, partly cut away to show the interior construction. Fig. 5 is a plan View of a blank cut and scored or creased adapted to be folded into a box or lid having the lock on its bottom instead of the sides. Fig. 6 is a plan view of a box formed from a blank shown in Fig; 5, partly cut away to show the bottom.

The blanks used consist of a substantially square or rectangular piece of cardboard, and the only loss in the way of material is the slight portions cut away to form the locks.

In the blanks as illustrated the dotted lines indicate the scores or creases and-the black lines indicate the cuts.

To form the box shown in Fig. 2 from the blank shown in Fig. 1, the portions A A are folded up at right angles to the bottom 13, and the sides D D are also folded up at right angles to the bottom B. The corner-pieces O C are then folded at right angles to the ends A A and the tongues 0 passed through the slots cl. (1 upward and downward, securely looking the sides together and holding the box firmly in shape. The parts cut away at the corners to form the tongues c are so formed when the two corners O O are brought together and the tongues c c inserted in the slots upward and downward that a very firm lock is secured, the portions 0 c, passing beneath the tongue of the opposite corner, serving to interlock and brace the joint with great firmness and security. In the blank shown in Fig. 3 the lock is on the top and the bottom. Thebox and lid are all in one, the portions F forming the four sides. The projection E may be pasted over the opposite end E,though that is not absolutelynecessary. The tongues G G pass up and down in the slots H H, and the tongues K K in the slots L L, forming the top and bottom and securelylocking,as shown in Fig. l. Figs. 5 and 6 are used in the construction of a deep boxsuch, for instance, as may be used for milliners hat-boxes-in which no lid is shown. The construction is substantially the same as in Figs. 4 and 5, except that the lid is omitted, and in order to give additional strength and firmness a flap P is added to be folded over and pasted in place as a reinforcement or stiffening.

It will be noticed that the tongues locking the folded box in form not only pass up and down in both directions, but that the same 0 slot is arranged to receive the tongue from the ends of both the opposite flaps. Thus there are two tongues passing through each slot and making a double lock. As best seen in Fig. 2, two tongues cpass through a single 5 slot, and these two tongues are part of the opposite flaps coming together and lapping over at the slot. 7

Having thus described my invention, what I claim, and desire to secure by Letters Fat ent, is-- 1. A paper box formed of a single square or rectangular piece of cardboard or paper,- its ends or sides or bottom reinforced and supported by flaps made integral therewith and having corner-pieces or t0ngues,these tongues overlapping the corresponding tongues on opposite flaps and passing together through 5 the same slot to produce a double lock, substantially as and for the purpose described.

2. In a paper box constructed of a single square or rectangular piece of cardboard, the

two interlocking tongues integral with the opposite flaps passing through a single slot IO producinga double lock, substantially as and for the purpose described.
